includes some fixes and improvements around RS485 in the serial core and UART drivers: Patch 1: Do not hold the port lock when setting rx-during-tx GPIO Patch 2: set missing supported flag for RX during TX GPIO Patch 3: fix sanitizing check for RTS settings Patch 4: make sure RS485 is cannot be enabled when it is not supported Patch 5: imx: do not set RS485 enabled if it is not supported Patch 6: omap: do not override settings for rs485 support Patch 7: exar: set missing RS485 supported flag Changes in v6: - restore RS485 GPIO settings if setting rs485 configuration fails (pointed out by Ilpo) - drop change for uart_get_rs485_config() - rephrase and correct commit messages (pointed out by Ilpo) - remove unnecessary structure nullification (suggested by Ilpo) - move all RS485 tasks into one function (suggested by Ilpo) Changes in v5: - do not combine the functions that set the RS484 GPIOs (as Hugo originally suggested) Changes in v4: - add comment for function uart_set_rs485_gpios after hint from Hugo - correct commit message as pointed out by Hugo - rephrase commit messages - add patch 7 after discussion with Ilpo Changes in v3 - Drop patch "Get rid of useless wrapper pl011_get_rs485_mode()" as requested by Greg Changes in v2: - add missing 'Fixes' tags as requested by Greg - corrected a typo as pointed out by Hugo - fix issue in imx driver in the serial core as suggested by Uwe - partly rephrase some commit messages - add patch 7 Lino Sanfilippo (7): serial: Do not hold the port lock when setting rx-during-tx GPIO serial: core: set missing
